useful Improvements in Bottle-Cap Pullers,

of which the following is a specification.

This invention relates to a cap puller for bottles and the form of myinvention disclosed in the following specification and in the drawingsis particularly adapted to be fastened to a stationary support, althoughI do not wish to be understood as limiting my invention to thisparticular embodiment thereof.

Broadly, the cap puller of my invention embodies two contact portions,one of these contact portions is adapted toengage a. portion of theunder edge of a cap of a bottle. The other contact portion is adapted tosimultaneously engage the central portion only of the bottle cap, thatis, that portion of the bottle cap which is in alignment with the boreof the bottle neck.

In bottle cap pullers heretofore con structed, the contact portion whichbears against the cap projects entirely thereacross and bears againstthe cap above the edges of the neck of the bottle, resulting in apressure being brought to bear upon the neck of the bottle when the capis being removed, which causes the same to chip, crush, or break.

It is one of the particular objects of this invention, therefore, toprovide a bottle cap puller which will not chip or break the neck of thebottle,"and this object is attained in the device of my invention by soconstructing the same that the fulcrum against which the cap presses, orwhich is pressed against the cap, is positioned in the central portiononly of the cap, and does not press on the cap above or in alignmentwith the neck thereof.

The invention consists in a cap puller embodying the construction setforth in the following specification and particularly inted out in theclaims.

Referring to the drawings:

Figure 1 is a vertical sectional elevation illustrating ,my improvedbottle cap puller attached to a stationary support, a portion of abottle being shown indotted lines-in the position in which it is placedwhen it is desired to remove a cap therefrom.

Fig. 2 is a front elevation as viewed in the direction of the arrow a,Figure 1.

Fig. 3 is a rear elevation view from the left of Figure 1.

Fig. 4 is a section taken on line 4-4, Figure 2.

Fig. 5 is a sectional elevation taken on line 5-5, Figure 2.

Like numerals refer to like parts throughout the several views of thedrawings.

In the drawings, 6 is the bottle cap puller of my invention illustratingthe same as positioned upon a fixed support 7, to which it is attachedby screws 8 which project through a base 9 and the upper end of an arm10. The base 9 has an ear 11 thereon which constitutes one contactportion of the cap puller, this portion constituting a fulcrum againstwhich the cap 12 of a bottle 13 rests when the cap is being removed fromthe bottle. The cap puller embodies another contact portion 14 whichconstitutes a lip provided upon the lower edge of an inverted U-shapedportion 15. The U-shaped portion 15 projects upwardly and outwardly fromthe base 9 and consists of two arms 16 and 17 connected together by anarched cross piece 18.

An inverted U-shaped opening 19 is provided in the cap puller andextends partly around the ear 11 and within the U-shaped invertedU-shaped portion 15 and terminatesin an ear 21, the rear face of the ear21 being in alignment with the rear face of the base 9. both of saidbases contacting with the rigid support 7 when the device is attachedthereto by means of the screws 8.

It will be understood that when the bottle is in the position shown indotted lines, Figure 1, that the diametrically opposite sides of the cap12 contact with the arms 16 and 17 of the U-shaped portion 15, while thelip 14 contacts with the under edge of the cap, so that the U shapedportion serves as a means for connecting the contact portion 11 and thecontact portion 14, and also serves as a means, together with said lip14, to position said cap with its diametrically opposite sidescont-acting therewith and with the central portion on y said fulcrumcontact portion.

The general operation of the device is as follows :Assuming the bottlecap puller tobe attached to a rigid support, the bottle is positioned asillustrated in Figure 1, in: dotted lines, with the lip 14 hearingagainst the under edge of the bottle cap for a portion of itscircumference and with the ear 20 bearing against the central portion ofthe cap as hereinbefore defined, and with diametrically opposite sidesof the cap engaging the arms 16 and 17. \Vhen in this position it willbe seen that the cap is positioned by means of the U-shaped portion ofthe device including the lip ll. and further positioned by the ear 11.Having thus positioned the bottle in the cap puller a downward movementupon the bottle will cause the cap to be removed from the bottle neck.

I claim:

1. A cap puller for bottles comprising a base adapted to beattached to asupport, a projection on said base constituting a fulcrum and adapted toengage the central portion only of a bottle cap on a bottle, means onsaid base adapted to partially encircle and position said cap relativelyto and laterally of said projection with a lip thereon to engage beneaththe edge of said bottle cap, there being an opening between saidpositioning means and projection through which a portion of said cap mayproject, whereby upon tipping said bottle on said projection the capwillbe removed from the of said cap contacting with bottle," and an armprojecting upwardly ,from said positioning means and inclined "inwardlyterminating in alignment with the inner face of said base and spacedapart therefrom, whereby said cap puller may he further attached to saidsupport.

2. A one piece cap puller for bottles comprising a base adapted to beattached to a support, an ear on said base projecting forwardly from theupper end thereof and constituting a fulcrum adapted to engage thecentral portion only of a cap on a bottle, an inverted U-shaped portionprojecting from said base outwardly around said ear with an openingtherebetween adapted to receive a portion of said bottle cap, a lip onthe lower edge of said U-shaped portion adapted to engage beneath theedge of said bottle cap, said U-shaped portion constituting a means forpositioning said ear relatively to the cap and laterally thereof,whereby upon tipping said bottle upon said ear the cap will be removedfrom the bottle, and an arm projecting upwardly from said U-shapedportion and inclined inwardly terminating in alignment with the innerface of said base and spaced apart therefrom whereby said cap puller maybe further attached to said support.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
